To all whom it may concern V Be it known that I, Bruce BLACKBURN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Screened Window, of which the following is a specification.

This invention relates to the art ofscreem ing openings such as windows and doors by means of a flezdble screen of wire cloth, and an object is to provide for a building, a screened opening, the mountings of which are concealed within the structure forming the opening and in which a wire cloth screen is provided and arranged to be drawn into and withdrawn out of screening position.

The invention includes in combination a frame structure for the opening to be screened, a spring actuated roller screen fixture and housing and also the combined fixture and housing and other parts and combinations of parts as-will more fully appear from the subjoined detail description. An object of the invention is to provide a frame structure and roller screen fixture in correlation to each other whereby it is made easy to install the fixture in and to remove it from thestructure as occasion may require and to form a novel construction and combination of screened-window elements.

-A further object of the invention is to provide a fixture that is adaptedto be easily.

and readily inserted into and withdrawn from said structure, and which-is adapted to he engaged by'the screen when closed, so as to close any opening due to unwindingthe screen from the roller.

Another object is to construct a fixture that is adapted to be easily changed to a slight extent so as to be" adjusted to fit snugly in the opening in the frame prepared therefor, thus toaccommodate slight inaccuracies of fit. Also to so construct the fixture that it is self-correcting as to adjustment in position in the housing; and to minimize the necessity of skilled labor for installing the screens. 7

In this invention I have produced a disappearing roller screen housing with a defiected outer edge. One of the objects of de- I Specification of Letters Patent.

gin of the cylinder to extend'toward the wire cloth so that when the screen is pull tirely down, said margin is touched by the screen cloth thus excluding flies, etc. The

deflected margin is so placed that when the screen is allowed to wind clear up it actsas the appended claims.

The fixture may be installed alternatively in a more or less .concealed position and various modes of installation will be illustrated.

The accompanying drawings illustrate the invention. a a

Fig. 16 is a fragmental plan section on line 2: of one side of the easement window frame shown in Figs. 15 and17.

Fig. 17 is a view analogous to Fig. 15 showing the screen and fixture practically concealed in a transom bar.

In the several views either the right or left side of the window is shown; it being understood that the two sides are alike as to the jambs, stops and screenways' which, as in usual constructions, are complementary to thoseshown.

Reference will first be made to the installation shown in Figs. 1', 2 and 3 in which the side jambs or 'pulley jambs 1 of the window frame is of well-known construction. The window casings 2, 3 and the blind stops 4 and split window stops 4 and 4" are also of well-known construction, and are in fixed relation to the ,ulley jambs.

The head jam b is formed of a plurality of sections as 5, 6, 7. The mainbody 5 of the head j amb is grooved as at 8, while the other sections, guards or closures 6, 7 are spaced apart at the mouth of a chamber formed partly by said sections 6, 7 and partly by the groove in the under side of the main head jamb section 5'. Sections 6, 7, are detadhable and are spaced apart to leave an opening 9 into the chamber 8 which is adapted to accommodate a roller screen fixture above the level of the lower face of the head jamb. The head jambsections 6 and 7 partially close the mouth 9 of the chamber 8 which is sufliciently large to allow the housing for a roller screen to be inserted when the closure sections 6 and 7 are removed. The front-detachable section, guard or closure 7 of the head jamb forms a head for the finishing members 4 of the divided window stop.

The opening 9 forms a screen-way extending from jamb to jamb and communicatingv at the ends with vertical screen-way grooves 10 extending between the window stop members 4, 4" to the bottom 9" of the opening to be screened.

The fixture includes a slotted housing com-. prising a nearly cylindrical case formed of a volutoid sheet 11 constituting the surrounding wall of the housing and having a longitudinal slot or slot-like downward opening 12 in one side from which the woven wire screen fabric or sheet 13 may be drawn between complementary brackets 14, 14 that are preferably stamped from sheet metal and fixed to the ends of the sheet 11. On the ends of said sheet projecting tongues 15 are provided; the same being adapted to pass through slits 16 cut in the brackets to accommodate said tongues. At one side of each bracket a rectangular flexible extension 17 is provided and thesame is perforated with holes 18, 19, 20 punched outward from the inside of the bracket to form countersinks for the heads of screws 21 that fasten the bracket to the side supports or pulley jambs 1. e

The brackets are secured in place on the cylindrical case by inserting the tongues 15 through the slits 16 and bending said tongues over on the outside of the bracket wall.

The roller is provided at its ends with the usual angular gudgeon 24 and the bracket 14 is provided with an angular slot 25 to receive the same. The centers of the brackets 14 and 14. are stamped to form the inwardly projecting bosses 26 punched to support said gudgeon 24 at one end of the roller and the pivot pin 27 at the other end of the roller; the second bracket 14 being provided with a circular hole 28 in its boss 26 to seat said pivot in. 1

To assemble the parts of the housing and to then assemble the roller screen therein, the first bracket member 14 is first applied to one end of the cylindrical case, inserting the wings 15 15 through the slits 16, and then bending said wings over upon the outside of said bracket member. Then the wire screen fabric is wound upon the roller and the spring given the appropriate tension in the usual way and the roller and screen are then inserted lnto the case allowing the fabric to slip edgewise along the opening 12 therefor; and finally inserting the pivot pin 27 into the hole 28 therefor. Then the second bracket member 14 will be applied to the open end of the case, the angular gudgeon 24 being inserted into the seat 25 therefor and the tongues 15 being inserted through the slots 16 therefor, and bent over upon the outslde of sald bracket member, thus securing the bracket memberon the sheet 11 and com pleting the fixture which may then be inserted throu h the opening 9 into the chamber 8.

One 0 the edges of the sheet 11 that con stitutes the wall of the case, is deflected outwardly to form a straight lip 31 projecting outward from the cylindrical portion of the case, so that the slot 12 directly overhangs the screen-way grooves 10; and the stop 30 may contact with the lip 31 so that the free end of the wire fabric is thus prevented from being drawn into the case by the action of the roller springs. Therefore, the roller spring may be given any desired tension at the time of installing the screen in the housing, and there is no likelihood of the tension thus given being changed so long as the spring retains its original resiliency. When the fixture is installed as shown in Fig. 4 th lip 31 serves as a stationary stop to receive the movable stop or handle 30.

As is particularly shown in Fig. 11, the stop 30 preferably constitutes a longitudinal bend upon a metal ,strip which is further bent longitudinally so as to form flat outer sections 29 and 29' joined by the lower edge of the strip, and a flat intermediate section 29", the lower edge of the screen 13 being securely clamped between the intermediate section'and the outer sections, and the end of the metal strip so formed slidingly fitting in the screen-way grooves 1.0. It should also be noted that the stop is above the lower edge of the metal strip, so that, when the screen is raised to its. stop-engaging position, any tendency of the stop 30 to tilt and to be drawn into the screen housing is prevented by the engagement of the ends of the metal strip with the screen-way groove.

The bracket 17, 17 are provided adjacent the lip 31 with a straight edge 32 extending vertically down from said lip and terminating at the lower edge 32 of the bracket, at right angles to said lower edge. The ad vantage of this construction is that when the fixture is mounted with its edge 32 in a vertical position the wire screen may be completely unrolled by pulling the free edge of the screen vertically and without rubbing the screen against the edge e at the margin of the slot 12. This is a desirable feature in the construction where the screen is mounted in the open as "shown in Figs. 4 and 14.

In the form shown in Fig. 1, whenthe screen is retracted, the stop 30 engages the head jamb or closure section '7 instead of the lip 31 which lip in Fig. 1 rests upon the top of the jamb section 7. When it is desired to apply the fixture to a window frame, the vertical straight edge 32 is brought into a vertical position determined by bringing it into parallelism with the vertical edge of the side jamb or casing, and the bottom straight edge 32' of the two brackets are brought to level position by locatin them at the same distance above the top 0 the side jambs or casing.

The edges 32, 32 of the bracket members are normal to each other and the edge 32 extends vertically downward from near the edge of the lip 31 to the bottom horizontal edge 32. To install the fixture, each of the side jambs 1 will first be marked with a horizontal line, not shown, each line being at the same distance from the head jamb, thus to indicate the location of the base line 32' of the bracket a shown in the drawing. Then the fixture is brought into place with the base edges 32 of its brackets on the lines, thus marked but not shown in the drawings. The vertical edges 32 are then brought to position equidistant from and in parallelism with the edges of the side jambs or casings. Then the screws 21 are inserted and driven home. In this way the time and labor of setting the fixture is minimized; the rectangular members or legs 17 17 of the brackets are laterally flexible, thus serving as gages to insure proper placing of the fixture.

In the form shown in Figs. 1 and 2 the lip 31 rests on or is adjacent to the top of the head jamb section or closure 7 after the same has been brought into position and fastened by the screw33.

After the brackets have been fastened in place by screws 21 in the double hung window in Figs. 1, 4, 12 and 14, a bumper block 34 is fixed in place-over the lower end of the bracket members 17 by means of screws 35, and the Window stops 4, are applied over a portion of the bracket members 17. The inner faces 36 of the window stop members 4: form one side of the guide-way 10 and are arranged vertically beneath the inner edge e of the volutoid sheet 11.

In the form shown in Figs. 4 and 5 the head jamb section 7 conceals only the upper portion of the case 11 and the lip 31 is open to view and serves as a stationary 110 stop for the movable stop 30 of the flexible screen 13.

In the form shown in Fig. 12 the head jamb section or closure 7 is a flat strip oblong in cross section extending across the window and fastened to the under-side of the main head jamb section 5 which is rabbeted at r to receive the section 7" and also the parting bead 37.

housing opening 12 presented toward the outside head casing 40 above the lower edge of the same. The head j'amb section 7 can be inserted and removed from its position below the fixture by first lowering the window sash 41 and then simply removing the screws 39 and the brackets 38.

In the form shown in Fig. 14 the cylindrical portion of thevolutoid case is set out beyond the outer head casing 42. It may be gained in or housed in the window structure more or less depending upon the thickness of the casing and of the walls. The cylindrical portion of the volutoid shell is exposed to the weather and protects the opening 12 which is presented inward toward the window sash 41. The runway 10 is made in this form by a single outer stop 43 and the usual blind stop 4, said outer stop 43 being fastened against the inner edge of the outside casing 44.

In the form shown in Fig. 15 .a construction for mounting a screen in connection with a casement window is shown. The casement window 45 in this view is arranged to open outwardly. The main head jamb section 5 is provided with a groove 46 in which the fixture case is mounted, the lower edge of the lip 31 being flush with the lower face of said head jamb section 5 and resting on the head j amb section of closure 7". The head jamb section 6" extends underneath the volutoid shell and is supported at its ends by a stop 47 which covers the major portion of the lower ends of the bracket members 17. An inside stop 48 extends under and supports the ends of the head Jamb section or closure 7 The guide-way 10 is formed between the stops 47 and 48 fastened to the side jambs 1.

In Fig. 17 the transom bar 54 takes the place of the main head jamb section 5 and is provided with a groove 49 in which the fixture is mounted in a manner analogous to that shown in Fig. 15.

The manner 'of'installing the invention in these different forms is apparent from the foregoing description.

The volutoid case is preferably constructed mainly as a cylindrical shell and in the views except Fig. 10, the character 11 is ap plied to the cylindrical part and in Fig. 10 it is applied to the part that becomes cylindrical in the completed fixture.

By combining the semi-cylindrical portion thus marked, with the outwardly deflected lip 31 the required rigidity is secured in the longitudinally slitted housing which allows the edge of the screen to be manipulated and drawn from and wound onto the roller 22 with a minimized liability of rubbing the screen; at the same time avoiding sharp bending of the screen and allowing the stop 30 to be intercepted without likelihood of wedging.

In practice, when the screen is drawn down to the window sill, not shown, the screen 13 will be so far unwound from the roller 22 that it will engage the edge 6 thus closing the slot against the admission of insects that might otherwise crawl into the housing and around the screen on the roller and thence in front of the screen through the slit into the building intended to be protected.

By arranging the edge e between the vertical edge 32 and a vertical line f drawn downward from the front edge of the roller in parallelism with the vertical edge32, the operation above set forth is effectual to exclude the flies, and the screen runs free from the edge during the latter part of the opening movement and the first part of the 010s ing movement of the screen. The nearer the edge e is to the vertical line f drawn from the front edge of the roller when the edge 32 is vertical, the reater will be the (screen travel without ru bing; and it is understood that the edge 6 may be located so far from the vertical edge 32 that when the screen is pulled down to the window sill, not shown, said screen may not touch the edge e. This might result from having considerably more screen on the roller than is required for closing the window opening and it is therefore desirable that the amount of screen on the roller should be only ample for closing the opening, and that theedge e be located just in front of a line drawn from the front edge of the roller in parallelism with the verticaledge 32, as is most clearly shown in Fig. 1.

By reason of the bendable tongues 15 extending through the slits 16 it is only necessary in order to remove the roller and attached screen for the purpose of repair and for any other purpose, to simply straighten the tongues 15 so that the bracket may be withdrawn from the end of the case, thus leaving the roller free to be withdrawn from the case to which it may again be returned and the bracket again fastened in place as before. A

It is thus seen that I have provided a practically concealed roller screen 22, 13 in the head jamb of a window structure and have also provided a window structure with a head jamb section grooved on its under side and have combined therewith a disappearing roller screen concealed in said grooved section by detachable head jamb sections as at 6, 7 and their equivalents shown in Figs. 12, 15 and 17 whereby the roller screen and its housing are easily installed and removed.

I claim 1. The combination with side jambs; of main, front and rear head jamb sections, the front and rear sections being spaced apart to form an opening; one of said latter two sections having a vertical edge presented toward said opening and forming a removable guard for said opening,there being a space at said vertical edge to form a screen-way between said edge and the other of the latter two' sections; and a roller screen housing comprising a case and end brackets, said case having a longitudinal slot with a deflected lip at one edge of said slot resting on the head jamb section having the vertical edge, above said vertical edge thereof; brackets at the ends of said housing, each having a vertical edge above the vertical edge of said head jamb section, and means to fasten the brackets to the side j ambs.

2. The combination with side jambs; of a head jamb constructed with front and back sections spaced apart to form an opening; one of the sections constituting a removable guard for said opening; said sections being arranged to provide between them a screenway through which a screen may be drawn; a roller screen housing insertible through said opening, and concealed by said guard; said housing being provided with end brackets and comprising a cylindrical slotted case having a deflected edge; said brackets being provided below said deflected edge with a vertical edge to serve as a gage for locating the housing relative to said sections.

3. The combination with a Window casing having a head jamb and side jambs provided with screen-way grooves, of a housing having at one side a longitudinal slot and an outwardly deflected, straight lip at one edge of the slot; a spring operated roller in the housing, a screen on said roller and a strip fastened upon the lower end of the screen and bent longitudinally so as to form flat outer sections oined by the lower edge of the strip, the ends of the strip slidably fitting in the screen-way grooves, and the strip also being provided with a longitudinal bend forming a handle and a stop above the lower edge of the strip to operate the screen and to between said vertical edge and a line drawn from the front ed e of the roller in parallelism with said straight edge.

5. The combination w1th a screen roller and a screen thereon; of a housing for said roller and screen; said housing being provided with a slot through which said screen may be drawn from the roller; and a guide for the screen, said guide being so located relatively to an edge of the housing at one side of the slot that only when the screen is drawn into the guide and mainly unwound from the roller the screen will contactwith said edge to exclude insects from the hous- 1n lin testimon whereof I have hereunto set my hand at os Angeles, California, this 17th day of October 1916.
